Haze may be making a comeback

The haze may have returned, judging from the unhealthy air quality in Kuala Selangor.
The Air Pollutant Index (API) released by the Department of Environment (DOE) for the town rose from 104 at 11am to 108 at 5pm yesterday.
The API was 79 at 5pm the previous day.
Kuala Selangor and Port Klang were in a state of emergency last month when their API breached the 500 mark.
Gombak also registered unhealthy air quality with an API of 101 at 5pm yesterday.
But the dominant pollutant in Gombak was ozone, which, according to notes accompanying the API data, could be produced from a reaction between industrial or vehicle emissions and sunlight.
Meteorologists said the two areas suffered the most from the haze because they were directly in the path of smoke blown over from Sumatran hotspots.
The API for Port Klang was 75 at 11am yesterday.
It increased to 80 at 5pm.
Other air quality monitoring stations registered good or moderate levels.
In Kuala Lumpur, it rose from 56 at 11am to 64 at 5pm, in Petaling Jaya it went from 61 to 65 and in Shah Alam it rose from 64 to 67.
The DOE said in a statement that the Asean Specialised Meteorological Centre’s satellite reported 78 hotspots in North Sumatra on Saturday.
